Supply Chain Expert & Engineer |Tech Sourcing | ISO Quality Management

In the age of AI, anyone can find a list of suppliers in seconds. But finding a factory that actually delivers what they promise—without hidden technical risks—is harder than ever. I bridge the gap between online data and what’s actually happening on the factory floor. Why Work With Me? I bring over a decade of "boots-on-the-ground" experience in complex machinery and electronics. I don’t just "middleman" deals; I use my engineering background and ISO quality standards to vet suppliers through a technical lens. I speak the language of engineers and the language of business, ensuring nothing gets lost in translation. I currently operate my own sourcing firm, providing professional-grade infrastructure for clients who need more than just a basic agent. How I Deliver Value: * Smart Sourcing & Factory Matchmaking: I combine AI market tools with my own technical database to match you with the exact right manufacturers. I don’t just look at prices; I evaluate their technical limits, specialized equipment, and alignment with your specific project requirements (e.g., dedicated production lines). * Technical Risk Control: I catch the "red flags" that standard sourcing agents miss—long before the deposit is paid. * Engineering Insights: Expert in DFM (Design for Manufacturing) feedback, cost breakdowns, and resolving complex technical discrepancies across global trade environments. * End-to-End Execution: From supplier qualification and factory audits to final quality inspections and shipping logistics. I bring structured thinking, bilingual precision, and a "zero-compromise" attitude toward quality. My goal is to protect your investment and ensure your supply chain runs like a well-oiled machine.
